调质是饲料制粒前进行水热处理、软化粉料的加工过程。在传统的饲料厂,制粒前的调质是较难操作的环节,而且任何单一的调质时间都不可能是所有饲料的最佳调质时间,因此需要对调质时间加以变动。人们很早就知道调质滞留时间对调质和制粒质量都有影响。在水产饲料加工中,通过调质? Quenching feed granulation before hydrothermal treatment, softening powder processing. In traditional feed mills, pre-granulation is a harder part of the process and any single conditioning time can not be the optimum conditioning time for all feeds, thus requiring a change in quenching time. It has long been known that quenched and tempered residence time has an effect on the quality of the quenched and tempered granulate. In aquatic feed processing, through the quenching and tempering?
